  • Patent number: 11414816
    Abstract: A method for treating a pulp web in a paper or tissue machine with an extended-nip press unit. This extended-nip press unit includes a shoe press roll with a revolving press belt and a backing roll, where the pulp web is dewatered in the extended press nip between the backing roll and the press belt and where the pulp web is carried on the revolving press belt of the press roll after the extended press nip to a transfer fabric that receives the pulp web. The transfer fabric is guided over a stationary transfer device in the transfer area. A corresponding device for treating the pulp web.

  • Patent number: 9885153
    Abstract: Disclosed is a device for forming an extended nip between a counter roll and a shoe roll for machining a material web, wherein the shoe roll has a support and a flexible roll shell, which can rotate around the support (4) and which rests in the region of the extended nip upon a head surface of a press shoe guided on the support, and the press shoe displaceably rests on the support in order to generate a press pressure via a pressure chamber to which fluid can be applied, the pressure chamber is disposed as a pressure pad, on which the press shoe rests surficially on the rear side, wherein the pressure pad is inserted into a groove-like chamber, wherein the press shoe has a stamp-like section on the rear side, which stamp-like section descends into an invaginable pressure pad in order to perform reciprocating movements, and the pressure pad is guidedly supported on the groove-like chamber along a pressure pad lateral wall that forms a roll wall.

  • Publication number: 20070060456
    Abstract: The invention relates to a roll for pressure treatment of material bands comprising a carrier (3), a roll sleeve (4) arranged on said carrier (3), and at least one pressure chamber (12) which is disposed between the carrier (3) and the roll sleeve (4), is at least partially filled with liquid and can transmit at least indirectly a hydraulic pressure force from carrier (3) to the roll sleeve (4). According to said invention, the pressure chamber(s) is provided with an elastic element (18?) which unrestrictedly communicates with supporting liquid and is compressible when a liquid pressure required for producing a supporting hydraulic force is exceeded.
